DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] As shown in FIG. 1 to FIG. 4, a bracket-type wireless charger provided by the invention comprises a box body 1 provided with a charging circuit and a transmitting plate 2 provided with a transmitting coil, wherein an adapter plate 3 is arranged between the transmitting plate 2 and the box body 1, an upper end of the adapter plate 3 is hinged through interference fit to a lower part of a back surface of the transmitting plate 2, and a lower end of the adapter plate 3 is hinged through interference fit to a middle part of a top surface of the box body 1, and the box body 1 is provided with a groove 11 for accommodating the adapter plate 3. The position and an inclination angle of the transmitting plate 2 relative to the box body 1 can be adjusted through rotation of the adapter plate 3, so as to adapt to the positions of wireless charging receiving coils of different electronic equipment, and the charging efficiency is ensured.
[0025] As shown in FIG. 4 to FIG. 6, the two ends of the adapter plate 3 are arc-shaped, the groove 11 at the top surface of the box body and a back surface of the transmitting plate 2 are provided with a recessed portion 4 fit with arcs 31 at the two ends of the adapter plate 3 respectively, and both sides of the arcs 31 at the ends of the adapter plate are hinged through interference fit to side walls in the recessed portion 4. The recessed portion 4 is internally provided with two parallel strip-type through holes 41, a transverse bar 42 between two strip-type through holes is provided with a positioning bump 43 protruding towards arc surfaces of the two ends of the adapter plate 3. The positioning bump 43 on the transverse bar 42 is supported against the arcs 31 at the ends of the adapter plate. The positioning bump 43 generates a resistance when the adapter plate 3 rotates. After moving to adjust the charging position, the transmitting plate 2 is uneasy to drive by the gravity of the electronic equipment 5 to change, so as to ensure the supporting and charging stability of the electronic equipment 5. Moreover, as the two ends of the transverse bar 42 are hollowed with through holes, the transverse bar 42 is pushed and pulled with an external force to generate certain elastic deformation, so that the resistance applied to the adapter plate 3 while rotating is not too large. It is difficult to adjust the transmitting plate 2. Moreover, the abrasion of the positioning bump 43 under friction can also be reduced, so that the service life is prolonged.
[0026] As shown in FIG. 4, the box body 1 is provided with a placing groove 12 fit with the shape of the transmitting plate 2, a bottom surface of one end of the placing groove 12 is provided with an equipment positioning groove 13 parallel with the bottom of the transmitting plate 2, and the equipment positioning groove 13 passes through the box body 1.

As shown in FIG. 7, when the charger is used, the transmitting plate 2 is pulled out of the placing groove 12; at this time, the equipment positioning groove 13 is exposed out, the back surface of the electronic equipment 5 is pasted on the transmitting plate 2, a bottom end of the electronic equipment 5 is supported against the equipment positioning groove 13, the inclination angle and position of the transmitting plate 2 are adjusted (as shown in FIG. 3) until the wireless charging receiving coil in the electronic equipment 5 is aligned with the coil in the transmitting plate 2, so that it is very convenient and is able to be suitable for charging all kinds of electronic equipment.
[0027] Preferably, as shown in FIG. 3, the bottom of the top surface of the transmitting plate 2 is provided with a notch 21, and the placing groove 12 is provided with a lug 14 fit with the notch 21. In an unused state, the lug 14 on the box body 1 just extends in the notch 21, and the transmitting plate 2 is positioned simply, so as to prevent the transmitting plate 2 from being touched innocently to open.
[0028] More preferably, as shown in FIG. 8 and FIG. 9, the bracket-type wireless charger further comprises a charging plug 6, wherein a bottom surface of the equipment positioning groove 13 is provided with a positive and negative electrode 7 electrically connected with the charging circuit, one end of the charging plug 6 is provided with a plug-in terminal 61 plugged in a socket of an electric appliance, while the other end is provided with a metal sheet 62 capable of being electrically connected with the positive and negative electrode 7, and the plug-in terminal 61 is connected with the positive and negative electrode 7 through a circuit arranged in the charging plug 6. When the electronic equipment 5 is not provided with the wireless charging receiving coil, and after the plug-in terminal 61 is plugged in the charging socket of the electronic equipment 5, the metal sheet 62 of the charging plug is flush with the positive-negative electrode 7 of the charger, and the transmitting plate 2 is adjusted to support the electronic equipment 5.
